The company had previously mentioned the threshold of "anyone with an iPhone 6 or later whose battery needs to be replaced", which seemed to apply to the in-house diagnostic tests it was running on handsets, recommending a replacement once the battery drops below 80-percent its initial capacity.

When a customer brings an iPhone into an Apple store citing slowness, an employee would typically run a diagnostic test on the phone. While this was created to prevent crashes on phones with aging batteries, iPhone owners are far from pleased that Apple has been slowing down their phones without telling them. So, the company is offering discounted batteries for customers in order to "regain the trust of anyone who may have doubted Apple's intentions", the post said.

When Apple announced it would replace those batteries for just $29 each, some were still anxious that their phones might not qualify for the fix. However, it now said customers can get the new battery already.

The clarification comes from an internal Apple memo obtained by iGeneration.

Now it has been revealed that Apple will replace any battery for the $29 fee in the iPhone 6 and above, this has been confirmed by the guys over at MacRumors. The fund owned 54,751 shares of the iPhone maker's stock after selling 5,720 shares during the quarter.

By failing to properly disclose at the time that the company had breached an implied contract with consumers, one of the suits says, by "purposefully slowing down older iPhone models when new models came out and by failing to properly disclose that at the time the parties entered into an agreement".
